Call For Participants

Research Description

The study we are conducting at the University of Utah, department of Neurology, School of Medicine is designed to examine the impact of photobiomodulation (PBM) therapy on persistent symptoms following a history of repetitive head impacts.  This therapy has been used for many decades to improve wound healing and pain associated with orthopedic injury.  Recent work has clearly demonstrated that PBM reduces inflammation, improves mitochondrial function, and leads to better cellular function.  Many of these effects have been demonstrated in both animal and human research using objective plasma biomarker data (i.e., inflammatory and mitochondrial biomarkers).  More recent work in patients with a history of head injury has been especially encouraging and our lab has begun a number of research studies to document the benefits of PBM using neuroimaging (MRI), cognitive testing, sleep measures, motor testing and mood/behavioral questionnaires.  It is our hope that this type of therapy would improve the overall functioning of participants in the absence of any negative side effects or adverse events.  If we continue to see improvements similar to previous research, we expect that PBM would be a very useful adjunctive therapy to more standard or traditional therapies in TBI.  

We are looking for individuals to take part in this research. Participation would require traveling to the University of Utah at the start and conclusion for pre- and post-testing. Participants would be given a device to treat at 20 minutes every other day for 8 weeks. After the 8 weeks of treatment the post test would be administered at the University. Following the testing, each individual participating would be given the option of continuing treatment long term. If interested and you have a history of repetitive head impacts with mild to moderate CTE-like symptoms, please contact me through this site.

  1. I’m interested in participating in the Call for Participants research trial. I have a history of repeated head impacts/concussions. I have symptoms associated with CTE.

  3. I would be interested in more information about this study for my son who is suffering from severe anxiety & depression that he blames on concussions.
    He had two pretty severe concussions playing high school football as a linebacker. He is 30 years old.

  5. I am very interested in participating in this study. I have had more than my fair share of concussions playing 4 years of HS football and 4 years of college football. Although I finished playing at age 22, I have experienced many symptoms that were mentioned in your article. My symptoms started at about age 45. Now, at age 55, after reading about CTE, and speaking with many of my teammates, I believe my symptoms are related to my concussions.
    THANK YOU for taking the lead to help others.

  7. We are interested in having our adult daughter, Christina, participate in this study. She has experienced several concussions of varying severity, including a severe concussion that caused her to miss a significant amount of school and suffer post-concussive syndrome. She has struggled with anxiety and depression ever since. The symptoms she has been experiencing the last several years sound like CTE. We are so grateful to learn about this!

  8. How do we volunteer? My son has all the mentioned symptoms as a result of a car accident when he was 16 and suffered severe head trauma. He is now over 40 and receiving disability because of his symptoms. Can you help us?
